JOURNAL-BEARING.

Specification of Letters Patent. Patented Dec. 10,1912. Application filed October 26, 1911. Serial No. 656,833.

incased within and secured to rotate with the roller 15. As plainly shown in the drawings, the bearings 12, 12' are open recesses, extending a distance from the top of the central portion 4 of the brackets, and are formed with a rounded bottom, for the reception of the journals.

Be it known that I, GEORGE J PULLOCK, a citizen of the United States, residing at Smock, in the county of Fayette and. State of Pennsylvania, have invented certain new and useful Improvements in Journal-Bearings, of which the following is a specification. 1 l

The presentinvention relates to improvements in journal bearings, particularly as applied to haulage rollers and cables.

The object of the invention is to provide a durable ournal support for rollers, known as haulage rollers, as customarily used on inclines in mines, and to provide simple means access to the journal bearing, either to dismount the roller, or change its and also for oiling the bearings.

The invention consists essentially in novel arrangements and combinations of parts as hereinafter set forth.

In the drawings I have illustrated one we ample, and a modified form thereof, of the best mode I have so far devised for the practical application of the invention.

plan view of an exemplifymg structure embodying the features of the invention, showing a roller journaled in brackets, and a cable passing over the roller, journal cap-plates being swung out of position to permit oiling of the bearing. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is an end elevation of Fig. 1 as seen from the right. Fig. 4 is a vertical transindicated at 12, the recessed bearing is closed. The upper portions of the bearings are closed by a pair of cap plates 16 and 17. These plates are plates 16 having a pair of openings 16, and the plates 17 having an opening 17 through which the bolts 10projcct, and the plate 17, in addition is formed with an open slot 17 toclose about one of the bolts 10. The bolts 10 and plates 16 and 17 are secured in place by means of the nuts 18.

To increase the life of the brackets I have found it convenient and desirable to provide duplicate recesses in each bracket, so that when the journal bearings of one set of recesses become worn, the roller and its journals may be shifted to the other set.

When the open recesses-forming bearings may be oiled by placing the spout of the oil can in the recesses, as seen in Fig. 2. When the closed recessed bearing 12 is used, oil holes 19 are utilized, these being provided'in the plates 16, and the oil can spout may be entered in these holes to feed oil to the bearings. To afford access to the 'oil holes 19 in the plates 16, the upper cap plate 17 may be swung on one of the bolts 10, as a piv'ot (seen in Fig. 1) thus uncovering both holes 19 and thebearing may be oiled.

In dismounting the roller, as for instance when shifting the roller from one bearing to. another, the nuts 18 are first unscrewed, and then the plateslG and 17 withdrawn from the bolts 10., The roller may now be bearing.

In the preferred embodiment of my invcntion I utilize two complementary brackets l .and 2, preferably of metal. Thesebrackets are formed with curved or sloping of the central portion 4, to permit smooth sliding of the rope or rope due to the accidental, and sometimes unavoidable, contact of the cable with the proper. foundation for the brackets is furnished and thebrackets may be secured thereto by meansof bolts 6 and nuts 7 and--thei brackets are further pro-- in its bearings, and the cap plates replaced to hold the journals in place. v

Having thus fully described my invention, what I' claim as new and desire to secure-by Letters Patent is The combination with a roller and its journals of a pair of brackets each formed with a recess to receive said journals, a pair of perforated, cap plates covering each recountersunk recesses Qtoaccommodate the bolts '10 and their heads ll respectively.
